Terminal says that com.pathplanner.lib.config does not exist, but it exists on the Official API website.

FYI you’ll need to be on the WPILib 2025 beta to use the latest beta version of PathPlannerLib. If you want to stay on 2024 WPILib, you can access the 2024 PathPlannerLib documentation using the wayback machine.
This doesn’t work like that. GradleRIO will only resolve one version of the vendordep, and if your project built without modifying the beta vendordep json, that means it resolved the 2024 version.
